Dial in your Dura-Ace disc brakes with the perfect hydraulic hoses with help from Shimano's BH90-JK-SSR Disc Brake Hose Kit. This handy kit hosts everything you need to dial in your brakes, whether you're installing new brakes on your ride, or switching your groupset to a new steed and want to freshen up your hoses along with the switch. Constructed from durable braided polyester, it resists expansion from pressure for positive lever feel and consistent stopping. The hoses are built to pair with Shimano mineral oil, and can be easily bled once hooked up to your brakes for smooth power and modulation.
